Gibraltar LBR-124 Quick-release Pin 5/16 in 4130 Steel

Product Description

The GIBRALTAR LBR-124 is a button-handle quick-release pin designed for fast, tool-free pin removal in mechanical assemblies, jigs, fixtures, and equipment mounting applications. The pin measures 5/16 inch in diameter with a usable length of 1.5 inches, and it is manufactured from 4130 alloy steel with a zinc-plated finish for corrosion resistance. The button-handle actuator allows single-hand operation, compressing the spring-loaded ball detents to release the pin from its mating hole. This part is suited for maintenance technicians, fabricators, and industrial service professionals who require reliable, repeatable pin retention without tools.

This quick-release pin is used in industrial and mechanical service environments where components need to be secured and released frequently. Typical applications include equipment guards, hinged panels, tooling fixtures, agricultural equipment, and structural assemblies. The 5/16 inch diameter and 1.5 inch usable length make it appropriate for light- to medium-duty connections where fast disassembly is a routine part of the workflow. It is sold individually.

Key Features

• Button-handle actuator enables tool-free, single-hand pin removal
• 5/16 inch pin diameter and 1.5 inch usable length for light- to medium-duty connections
• 4130 alloy steel construction for strength and durability
• Zinc-plated finish provides corrosion resistance in general service environments

Compatibility

Designed as a replacement or spare quick-release pin for mechanical assemblies, fixtures, and equipment that accept a 5/16 inch diameter quick-release pin with a 1.5 inch usable length.

Installation Notes

Installation requires no tools — compress the button handle to retract the ball detents, insert the pin through aligned holes in the mating components, and release the button to lock the pin in place. Verify that the mating hole diameter is sized appropriately for a 5/16 inch pin before installation. Inspect the spring and ball detents for wear or deformation during routine maintenance. Remove the pin only after confirming the assembly is safely supported and not under load.
